Centrality features

In this exercise, you will compute and extract the centrality features betweenness, closeness, and eigenvector centrality.

XP

1
Extract the normalized betweenness of the nodes using betweenness(). Add it as a node attribute called betweenness.
2
Extract the normalized closeness using closeness() and add it to network as a node attribute called closeness.
3
Extract the scaled eigenvector centrality using eigen_centrality() and add its vector attribute as eigenCentrality.
